Benefits of technology

This patent describes a machining tool for cutting work components that includes a cutting tool body and a cutting tool insert rotatable between different positions. The tool has a cutting surface exposed in each position and can be inserted into different cartridges for use. The cartridges can be rotated to different positions for more precise cutting and the tool can be easily removed from one cartridge and inserted into another for use in different situations. The technical effects include improved precision and flexibility in machining work components.

Problems solved by technology

The high hardness cutting surfaces of the inserts may become dulled after as few as two uses, at which point they may be spent or used in a roughbore machining process.
The materials required for these finebore machining processes, such as artificial diamond or cubic boron nitride, can be costly to produce.

Embodiment Construction

[0025]FIG. 1 is a view of a machining tool 10 used to cut a work component. The description below will reference one part of the machining tool 10, but it should be understood that the embodiments described herein may be applied in bulk terms as illustrated in FIG. 1.

[0026]FIG. 2 is perspective view of a plurality of cartridges 12, 14, 16, 18, 20 for use with the machining tool 10 illustrated in FIG. 1. Each of the cartridges 12, 14, 16, 18, 20 is designed to be inserted into the cutting tool body 22 of the machining tool 10. Each of the cartridges 12, 14, 16, 18, 20 includes an insert pocket 24 for receiving a cutting tool insert 26. Although illustrated as including five cartridges 12, 14, 16, 18, 20, machining tool 10 may include any number of cartridges that allows the machining tool 10 to function as described herein.

[0027]FIGS. 3-7 are views of the cutting tool insert 26. The cutting tool insert 26 is a generally in the shape of a triangular prism with rounded vertices 28, 30,...

Abstract

A machining tool for cutting a work component includes a cutting tool insert having a cutting surface along a portion of an external surface that defines a circumference of the cutting tool insert. A plurality of cartridges are insertable into the machining tool, each having an insert pocket for receiving the cutting tool insert. The cutting tool insert is rotatable between first, second and third fixed positions in each insert pocket of the plurality of cartridges, a first portion of the cutting surface exposed when the cutting tool insert is in the first fixed position, a second portion of the cutting surface exposed when the cutting tool insert is in the second fixed position, and a third portion of the cutting surface exposed when the cutting tool insert is in the third fixed position. The insert pocket of each of the plurality of cartridges is offset from each other.

Description

TECHNICAL FIELD[0001]The embodiments described herein relate to the field of machining tools capable of cutting a work component.BACKGROUND[0002]Cutting tools with cutting tool inserts that include cutting surfaces with high degrees of hardness are used in finebore machining processes. The high hardness cutting surfaces of the inserts may become dulled after as few as two uses, at which point they may be spent or used in a roughbore machining process. The materials required for these finebore machining processes, such as artificial diamond or cubic boron nitride, can be costly to produce. Therefore, there is a need for a system that extends the life of the cutting tool inserts to maximize the usage of a single cutting tool insert in a finebore, or high precision, machining process.APPLICATION SUMMARY[0003]The features and advantages described in the specification are not all inclusive and, in particular, many additional features and advantages will be apparent to one of ordinary ski...
